7 Claims. (Cl. 242-18) This invention relates to textile machines andrelates more particularly to an improvement in the take-up means oftextile machines on which are produced cheeses and like packages ofyarn.

In winding or twisting and winding machines for producing yarn packages,as heretofore commonly constructed, the yarn was wound into packageformed by means of a cork-covered roll or drum which frictionallyrotated the yarn package. The positively driven cork-covered roll ordrum often caused excessive friction'on the yarn being wound whichresulted in broken filaments and hairy yarns. It is, accordingly, animportant object of this invention to provide an improved take-up meansfor a winding or twisting and winding machine which will be free fromthe above mentioned. and other disadvantages, and

. which will be especially simple in construction and ,efilcient andinexpensive in operation.

Another objectof this invention is the provision of a winding ortwisting and winding machine for producing packages of yarnwhich areperfectly wound as to the density and traverse and which will besubstantially free from broken filaments.

A further object'of this invention is the provision in a winding ortwisting and winding machine of an improved take-up means wherein thepackage being wound is directly driven.

Other objects of this invention, together with certain details ofconstruction and combinations of parts, will appear from the followingdetailed description. 7

In the accompanying drawings wherein a Preferred embodiment of myinvention is shown,

Figure 1 is a front elevational view of a portion of a twisting andwinding machine in which my invention is embodied, and

Figure 2 is an end elevational view, partly in section, of Figure 1.

'Like reference numerals indicate .like parts throughout both views ofthe drawings.

Referring to Figure lot the drawings, there are shown some of thetwisting and winding units generally making up a machine of this type.However, in order to simplify the disclosure of my invention, thedescription will be particularly directed to one of said twisting andwinding units such as is shown in Figure 2.

The yarn 3 to be twisted and wound into the form of a cheese 4 is drawnfrom a bobbin 5 drivingly supported by spindle 6 driven by any suitablemeans, such as a motor (not shown) through a belt or tape I passing overwhorl 8 and idler pulley 3 and driving pulley II, which pulleys are u'of the spindle, as is well understood in the art.

. a 2 a suitably supported on, the machineframework. The yarn 3 is drawnfrom' bobbin 5 througha fixed guide l2 supported on a cross-piece l3attached to the framework of the machine, said guide eye beingpositioned centrally or substantially centrally over the spindle 6. Fromthe guide eye l2 the yarn passes from a traverse guide I! carried by atraversing rod l5 whichtraverses the yarn on to the cheese 4.

The cheese 4 is wound on a yarn support or core It held on a mandrel I!"provided with spring. fingers H! for retaining the core on the mandrel.

The mandrel I'lis attached to a support l9 having integral therewith asprocket 2|, the mandrel and support assembly being mounted on ballbearings 22 mounted on a spindle blade 23 joumalled in a bearing member24 in the end of an arm 25. The sprocket 2| is connected by means of anarticulated chain 26 to the sprocket 21 mounted on the shaft 28 drivenby the output shaft of a positive, infinitely variable speedtransmission (not shown) such as the one known as a P. I, V?

gear manufactured by the Link-Belt 00. As is well known, such a variablespeed drive is so con- 5 structed and arranged that changes in speed may.be effected continuously during the operation thereof. By the use ofsuch a Variable speed arrangement, the cheese 4 being rotated by themandrel l1 may be given the constant peripheral speed which is necessaryto produce satisfactory cheeses. The shaft 28 is journalled in suitablej bearings carried on the upper extremities of standards 28' supportedon the framework of the machine.

For taking up the yarn 3 on to the package to form the cheese 4, themandrel II with a core or yarn support It thereon is placed in contactwith a polished steel drum 2!! having roller bearings 3| rotatablymounted on a stationary shaft 32, the rotation of the mandrel alsorotating the drum 29. The use of the idler drum 29 for supporting thepackage being. wound is advantageous since it makes for very littlefriction on the yarn being wound thereby substantially eliminatingbroken filaments and hairy yarn.

.As is shown in the drawings, means may be provided for lowering thepackage support on to the yarn and for automatically lifting the cheese.Such means is generally indicated by reference numeral 33 and is mquntedon the framework of the machine, being attached at one end to arm 25 andat the other end to a foot pedal 33'. A spindle brake' generallyindicated by reference numeral 3 is provided for stopping the rotationThe reference numeral 35 indicates drop wires which may be employed tostop the rotation of the yarn package upon the breaking or failure ofthe yarn.
